Erysimum plant named ‘ERFZ0001’

ABSTRACT

A new  Erysimum  plant named ‘ERFZ0001’ particularly distinguished by the purple-violet flower color, medium green foliage color, rounded and compact plant habit with good branching and is early to flower.

Latin name of the genus and species of the plant claimed: Erysimumlinifolium.

Varietal denomination: ‘ERFZ0001’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Erysimum, botanically known asErysimum linifolium, and hereinafter referred to by the variety name‘ERFZ0001’.

‘ERFZ0001’ is a product of a planned breeding program. The new cultivar‘ERFZ0001’ has purple-violet flower color, medium green foliage color,rounded and compact plant habit with good branching, and is early toflower.

‘ERFZ0001’ originates from a hybridization made in a greenhouse in April2009 in Enkhuizen, The Netherlands. The female parent was a commerciallyavailable plant identified as ‘Bowles Mauve’, unpatented, with mauveflower color, fewer branches, and overall larger size than that of‘ERFZ0001’.

The male parent of ‘ERFZ0001’ was an unpatented, proprietary plantidentified as ‘M1702-82’ with dark lilac flower color, is later toflower and less vigorous than that of ‘ERFZ0001’. The resultant seed wassown in September 2009 in a greenhouse, in Enkhuizen, The Netherlands.

‘ERFZ0001’ was selected as one flowering plant within the progeny of thestated cross in April 2010 in Enkhuizen, The Netherlands.

The first act of asexual reproduction of ‘ERFZ0001’ was accomplishedwhen vegetative cuttings were propagated from the initial selection inthe April 2010 in a controlled environment in Enkhuizen, TheNetherlands.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plantinitiated in April 2010 in Enkhuizen, The Netherlands, and continuingthereafter, has demonstrated that the combination of characteristics asherein disclosed for ‘ERFZ0001’ are firmly fixed and are retainedthrough successive generations of asexual reproduction.

‘ERFZ0001’ has not been observed under all possible environmentalconditions. The phenotype may vary significantly with variations inenvironment such as temperature, light intensity, and day length.

Plant Breeder's Right for this cultivar were applied for at theCommunity Plant Variety Office on Oct. 25, 2012 (2012/2346) and inCanada on Apr. 19, 2013 (13-7998). ‘ERFZ0001’ has not been made publiclyavailable more than one year prior to the filing of this application.

The following traits have been repeatedly observed and are determined tobe basic characteristics of the new variety. The combination of thesecharacteristics distinguishes this Erysimum as a new and distinctvariety

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawing shows typical flower and foliagecharacteristics of ‘ERFZ0001’ with colors being as true as possible withan illustration of this type.

The photographic drawing shows in FIG. 1 a flowering plant of the newvariety and in FIG. 2 a close-up of a flower and buds.

DETAILED BOTANICAL DESCRIPTION

The plant descriptions, measurements and aforementioned photographs weretaken in Gilroy, Calif. in March 2013 under natural light. These plantswere growing in an outdoor trial under natural light in Gilroy Calif.The plants were about 24 weeks of age.
